A Physiologically-Based Framework for the Simulation of Skin Tanning Dynamics

Images illustrating the visible skin appearance (left) and the corresponding ultraviolet appearance (right) of an individual with a low level of constitutive pigmentation and low tanning ability before and after a UVR exposure schedule equivalent to 30 SED. The top row depicts the pre-exposure appearance with an effective sunscreen applied to one side of the individual's face (depicting a glossier appearance). The bottom row depicts the appearance contrast between the untanned and tanned sides of the face 15 days after exposure.
